SPECIFICATION forming part of Letters Patent No. 625,580, dated May 23, 1899.

Applicationiiled January 23, 1899. Serial No. 703,100. (No model.)

To @ZZ w/wm t may concern:

Be it known that I, JOSEPH A. MANAHAN, a citizen of the United States, residing in New York, borough of Manhattan, in the county and State of New York, have invented new and useful Improvements in Sash-Balances, of which the following is a specification.

By means of this invention a window can be automatically or easily operated, as set forth in the following specification and claims and illustrated in the annexed drawings, in Which'- Figure lis a front elevation of the Window, parts being sectioned. Fig. 2 is a section along a; Fig. l. Fig. 3 is a section along y y, Fig. l. Fig. 4 is a section along z z, Fig. 1. Fig. 5 is a detail view of the bracket for the lower sash.

To the upper sash 1 is secured a brace or bracket 2, having a neck portion 3 and an arm 4. From arm 4 a rod 5 extends down` wardly and passes through lock 6. This lock is a sleeve having a longitudinal bore or passage and a transverse cut or bore. Into the transverse cut is placed pivot 7, which has a vperforation corresponding with the perpen- `portion 6, and there being no clear or unbroken passage the rod 5 cannot move up or down, but remains jammed or in fixed position. The rod 5 being of one piece with or secured to arm 4, which latter is attached to the window-sash l, the latter will be firmly held at a height relative to the positon of rod 5 when it is locked. Arm 4 has at its outer end an eye 4', so that it can slide along guide-rod l0, and around which rod is coiled spring 11, which furnishes the power for the automatic operation of the window.

Both sashes are operated in like manner, the arm 4 of the lower sash l also being provided with an arm or bracket 4, differing from the arm 4 of the upper sash by having a depending shank 12, Fig. 5, so that the eye part 4 is dropped or carried to the lower part of sash l', and a spring l1 of some length can be used for such lower sash, such spring ll being shown connected to the eye part 4 on shank l2.

Fig. l shows both sashes in closed position, the power-springs 11 being drawn or extended. When it is desired to open one or the other sash, button 8 is pressed against action of spring 9, so as to turn pivot 7 in lock portion 6, and thus bring the hole in said pivot in strict alinement with the perpendicularbore in lock portion 6. This will free the lock bar or rod 5 and provide an unbroken passage for such rod, and the latter passing therethrough' is forced along by the power-spring 11, together with the sash, so as to move up or down, and when at proper height the pressure on button 8 is released, the handle 8 is held at an angle by spring 9, the pivot or clutch 7 is thereby jammed or moved, breaking the passage in lock portion 6, and the rod 5 is arrested and locked, and the window or sash is thus firmly held at the desired height. A slit 3', Fig. 3, is cut through or along the window-casing for the passage of neck 3, permitting the latter to move up and down.

The guide-rods 10 or their carriers 14 are xed or secured to suitable parts of the casing, as are also the tubes` or lock portions 6.

The springs ll can be of such strength or tension as to move the sashes, or such springs could be arranged to simply hold or counterbalance the sashes, so that the latter can be easily moved by hand. Antifriction-rollers l5 opposite the brackets 2 canbe made to ease the travel of the sashes. The bracket `2, with its locking-rod 5 steadied by the guide or eye 6, in connection with the guide-rod 10, tends to keep the sash steady or levelled, so

that with ordinary weight-sashes the anti-` friction-rollers l5 will lnotbe needed. The closure of the sashes is effected by hand, while on pressing one or another of buttons 8 either the lower sash will rise or the upper sash drop to open the Window. The lock 6 7 can act at any point to lock a sash when closed, open, or partly open. Arelief-spring 16 on rod 5 can cause the bpening sash to be gradually arrested. To prevent the arm 4 wearing the woodwork in its motion such IOO Woodwork could be reinforced by brassor justable or extensible to set the buttons at desired heights.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination with a sash, of a bracket secured thereto, a spring acting on a part of the bracket, a locking-bar extending from the bracket, and a'lock through which the locking-bar slides longitudinally and by which said bar is locked in any desired position, subp stantially as described.

2. A sash having a bracket, a spring connected to the bracket, a locking-bar, a clutch, and a spring normally holding the clutch in locking position substantially as described.

3. The combination with a sash, of a bracket secured to one corner thereof and provided with a vertical locking-bar and a projecting guide-arm, a guide-rod on which the said guide-arm moves, a spring arranged on the guide-rod and acting against the guide-arm, and a lock through which the said lockingbar slides longitudinally and by which said bar is locked in any desired position, sub= stantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
